Abstract

In one example, a filtered feedthrough assembly for a medical device, such as, e.g., an implantable medical device, is described. The filtered feedthrough assembly may comprise a feedthrough comprising at least one feedthrough conductive pathway extending between a first feedthrough side and a second feedthrough side; a capacitive filter array comprising at least one filter array conductive pathway extending between a first filter array side and a second filter array side, and at least one capacitor filter substantially surrounding at least a portion the at least one filter array conductive pathway; and at least one electrically conductive member electrically coupling the at least one filter array conductive pathway to the at least one feedthrough conductive pathway.
